spring跟struts的整合步骤

1.加入jar包

复制文件。

复制struts2-spring-plugin-x-x-x.jar和spring.jar到WEB-INF/lib目录下。其中的x对应了Spring的版本号。还需要复制commons-logging.jar、struts2-core-2.3.4.1.jar文件到WEB-INF/lib目录下。

2. 配置web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"

        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

  <display-name>game.cai</display-name>

  <filter>

    <filter-name>encodingFilter</filter-name>

    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

    <init-param>

      <param-name>encoding</param-name>

      <param-value>utf-8</param-value>

    </init-param>

    <init-param>

      <param-name>forceencoding</param-name>

      <param-value>true</param-value>

    </init-param>

  </filter>

  <filter-mapping>

    <filter-name>encodingFilter</filter-name>

    <url-pattern>/*</url-pattern>

  </filter-mapping>

  <!-- 配置struts2-->

  <filter>

        <filter-name>struts2</filter-name>

        <filter-class>

          org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

        </filter-class>

    </filter>

    <filter-mapping>

        <filter-name>struts2</filter-name>

        <url-pattern>/*</url-pattern>

    </filter-mapping>

    <!-- 配置spring监听器-->

    <listener>

    <listener-class>

      org.springframework.web.context.ContextLoaderListener

    </listener-class>

</listener>

<!-- 用来定位Spring XML文件的上下文配置 -->

<context-param>

    <param-name>contextConfigLocation</param-name>

    <param-value>

        classpath:/applicationContext*.xml

    </param-value>

</context-param>

 <filter>

        <filter-name>hibernateOpenSessionInViewFilter</filter-name>

        <filter-class>

          org.springframework.orm.hibernate3.support.OpenSessionInViewFilter

        </filter-class>

    </filter>

 <filter>

        <filter-name>struts2CleanUpFilter</filter-name>

        <filter-class>

          org.apache.struts2.dispatcher.ActionContextCleanUp

        </filter-class>

    </filter>

  <welcome-file-list>

    <welcome-file>index.html</welcome-file>

    <welcome-file>index.htm</welcome-file>

    <welcome-file>index.jsp</welcome-file>

    <welcome-file>default.html</welcome-file>

    <welcome-file>default.htm</welcome-file>

    <welcome-file>default.jsp</welcome-file>

  </welcome-file-list>

</web-app>

3.添加struts2-spring整合的插件:struts2-spring-plugin-2.0.12.jar,如果不使用这个插件，则需要在struts.xml里面配置:

<constant name="struts.objectFactory" value="org.apache.struts2.spring.StrutsSpringObjectFactory" />
